A requirement in certain Facebook groups, for new members to post either a meme relevant to the group or a screenshot of the conversation that brought them there.

It encourages interaction within the group, which also means that the group's posts are more likely to be seen by other members, and an active group is more likely to be tagged in future discussions.

Named for Ursula the Sea Witch, from The Little Mermaid. Just like her, the group's admins have the power to take away individual member's voices (by muting them) if they fail to follow the "contract" they agreed to. Originally found in Disney-themed groups, the term has grown legs (hah!) and is now seen here and there around Facebook.
I joined a group that makes fun of mansplaining, and for the Ursula tax I posted a screenshot of the mansplainer getting dragged.
